5766: Hacky support for fn-like proc macros r=matklad a=jonas-schievink
It turns out that this is all that's needed to get something like this working:
```rust
#[proc_macro]
pub fn function_like_macro(_args: TokenStream) -> TokenStream {
TokenStream::from_str("fn fn_success() {}").unwrap()
}
```
```rust
function_like_macro!();
fn f() {
fn_success();
}
```
The drawback is that it also makes this work, because there is no distinction between different proc macro kinds in the rest of r-a:
```rust
#[derive(function_like_macro)]
struct S {}
fn f() {
fn_success();
}
```
Another issue is that it seems to panic, and then panic, when using this on the rustc code base, due to some issue in the inscrutable proc macro bridge code.
